Light curves in the NSVS (Northern Sky Variability Survey) are analyzed for their variability.
The NSVS covers the optical magnitude range from 8 to 15.5 for the Northern Sky. If light curves have good
photometric data points more than 15, these light curves are included in our analysis. The total number of
light curves in the current database is 16,189,040. This online database provides variability
analysis and objects' spatial matching to other databases such as SIMBAD, IRAS, AKARI,
WISE, 2MASS, SDSS, and GALEX.
In future, we will have more results of cross-correlations to future data.

In particular, the second paper explains all variable candidates found in the NSVS data with their associations to other observation data. Please, cite the above papers when you use our analysis results.
